Stipple shading is used in all of the accompanying Figures to convey surface contouring and not texture. The broken lines shown in the drawings illustrate portions of the attachment mechanism that form no part of the claimed design. Surfaces that do not include stipple shading and are bounded, at least in part, by broken lines form no part of the claimed design. 

CLAIM We claim the ornamental design for an attachment mechanism, as shown and described.
